Datei lässt sich nicht herunteralden

Can you include a screenshot of the error message?
What type of file is it? Is it big? Does it contains a lot of pages
Have you tried on another browser? (accepted browsers are Edge, Firefox, Safari and Chrome)
Have you tried clearing your cache?

It's always super helpful to include a screeshot of your full window when you create a bug report because the cause will be easily identified while without it, you are less likely to get any answers .
